Does anybody know what this button is for on the back of the intake manifold on my 5.3L?

It's where the brake booster connects to the intake. Mine is plugged with a cap since I have hydro boost. I don't remember if I had the plug or not.

Hmmm? Interesting. I too have the hydro boost just wondering why they wouldn’t just plug it. The button pushes in and comes out with a click.

I think the button works as a cap, but I plugged it just in case. If you pull it out it will probably cause a big vacuum leak.

Everytime you press it some random chick on the other side of the country creams her jeans....
It pushes in and pops back out like that because that's the spring keeper that holds the button in, which is actually a plug. The vacuum hose that goes there has the same kind of a keeper but it's easier to remove; you just squeeze the thing. It's the same kind of keeper that the fuel line quick-connects use. I'm thinking they figured you wouldn't be taking that off and on so they made it to where you need a tool to release it, like the fuel lines.

If you press that button it makes your 5.3L go to the output of a 6.0L. But you have to do the michael jordan tongue to the side thing while you are pushing the button for it to work right. Oh and have to take a vid of it and put on youtube so all others will know how to do it too.
